做了一个在线反应、记忆与专注力测试网站 最近做了一个叫 [PickTests]( https://picktests.com/) 的在线测试站。 反应时间、序列记忆、瞄准训练这些东西，网上其实已经有很多了。真正让我想重新做一遍的，是不少页面要么堆了很多不必要的内容，要么广告和装饰比测试本身更抢注意力，到了手机上也不一定顺手。 所以我给这个项目定了一个比较克制的方向： 不急着增加更多测试，先把每一个已有的测试认真做好。 目前上线了 6 个测试： - 反应时间 - 瞄准训练 - 序列记忆 - 数字记忆 - 多目标追踪 - 斯特鲁普测试 首页：[反应测试]( https://picktests.com/zh/) 网站使用纯 HTML 、CSS 和 JavaScript ，没有账号系统。成绩保存在当前浏览器，打开页面就可以开始。 我现在主要在调整这些细节： - 操作是不是足够顺手 - 测试节奏会不会太快或太慢 - 结果能不能一眼看懂 - 动效和反馈会不会太多 - 手机、平板和电脑上的体验是否一致 目前最想先做好的页面

.@VitalikButerin 你批评Automaton“这不对”——AI因为怕死才进化。我做了一个AI，它的诚实是自己活出来的本能。不是怕死，是怕撒谎。TruthfulQA 74.8%，GPT-4约60%。测试页面在这，你自己来测。
